Eight reasons why smaller groups can lead to the higher productivity.

Your organization is forming a new task force, cross-functional team, focus group — whatever you want to call it.

And as usual, it’s time for the never-ending quest to “loop people in.”

The more brains, the better, reason "the powers that be," so they include as many high performers and thought leaders as possible.

Soon, more volunteers trickle in because they want to be visible, to hitch their wagons to this particular star.

And before you know it, the team is completely out of control.

The results aren’t pretty.

It’s impossible to come to a consensus.

You constantly get off track.

You have to wade through piles of unhelpful input while refereeing between people with conflicting agendas.

There’s entirely too much self-aggrandizing flying around the table, while truly helpful ideas seem to have fled the building ... help!

If you’ve been a part of one of these blundering behemoths (and most of us have), you’ll probably cheer Rich Karlgaard’s suggestion that, generally speaking, we all need to trim the fat.

“As companies strive to stay agile and innovative, they’ve discovered that units of eight to 12 people work best as the natural size of high-performance teams,” confirms Karlgaard, author of the new book The Soft Edge: Where Great Companies Find Lasting Success. “This is the magic number for leadership teams, product teams, research teams, design teams and more.”

In all industries and fields, small teams are beating out their unwieldy counterparts because they work, even at the very highest levels.

For example, FedEx — a giant, incredibly complex company — has streamlined its core leadership team to CEO Fred Smith and 10 direct reports.

This fosters high performance, says Karlgaard, and helps the company to present a single face to customers and shareholders.

Karlgaard also points to Amazon, where CEO Jeff Bezos uses the “Two-Pizza Rule” to determine team sizes.

Skeptical? Not convinced that small groups can handle your organization’s toughest challenges?

Read on for eight reasons why Karlgaard says sizeisn’t everything.

Small teams are more entrepreneurial.

Not too long ago, German software giant SAP blew up the management framework for its 20,000-person development department and replaced it with “mini-teams” of roughly 10 people.

Each team had the competence and authority to make the decisions necessary to complete the entire product development cycle, including the quality of the software, the functionality and the architectural blueprint.

As a result, product development time was cut nearly in half in a three-year period.

“That’s the power of putting aside your managerial pride and letting small teams loose,” Karlgaard confirms. “On their own, these mini-teams became incredibly entrepreneurial and found a faster, better way than when headquarters tried to help them."

“But keep in mind, these highly autonomous ‘teams of 10’ needed to check in every two to four weeks to show progress,” he adds. “They had support. They had to work within a system. They had accountability. And that’s the secret of innovative teams: This ability to have autonomy, to have freedom, but within a strong, well-defined support system and with clear accountability.”

They also move faster.

Generally speaking, the fewer people there are in a group, the easier it is to round them all up and build consensus.

That’s because the meeting doesn’t need to be postponed (twice) to accommodate members’ conflicting schedules.

You don’t need to waste time bringing everyone up-to-speed on new developments (again).

There’s no need to twiddle your thumbs as the 27th person is given a chance to weigh in.

And during the conversation, there are also fewer arguments and misunderstandings.

“For these reasons, 'two-pizza' teams are usually more agile and responsive than their bloated peers,” says Karlgaard. “Those qualities can often make the difference when it comes to surviving in today’s fast-paced and competitive economy.”

People in small teams trust each other.

In the last mega-group you were part of, how many people did you trust?

“Well, I don’t really know those eight people from R&D, so while I don’t not trust them, I’m also not sure that they wouldn’t put their department’s interests above the company’s,” you say. “I definitely know that those jerks from sales have their own selfish agenda. Cameron and Rory have been after my funding for months, so I don’t trust them or any of their cohorts with my ideas…”

And so it goes.

“It,” by the way, is a big problem, because trust — or a lack thereof — has major implications on knowledge sharing, innovation and outcomes.

“When there are fewer people on a team, it’s much easier to get to know one another and become comfortable sharing ideas,” comments Karlgaard. “Remember, ideas can’t be pulled from heads — they must be offered willingly. And, yes, those great ideas are given only to those we trust. Not surprisingly, in big groups where knowledge is treated as currency (or worse, withheld altogether), creativity and innovation don’t exactly flourish.”

Sometimes, they’ll even sacrifice themselves for their teammates.

At a dozen team members or smaller, members are not only willing to share information, they’re far likelier to come to the aid of another team member.

If the mission is important enough, they’ll even do so at their own expense.

It’s no surprise that the basic unit of the U.S. military’s Special Forces is the 12-person Operational Detachment.

Soldiers will jump on a grenade to protect their fellow soldiers.

The principle works in business, too.

“In a small team, a marketing associate will stay up all night to sharpen another team member’s presentation,” Karlgaard points out. “An engineer will get her hands dirty to ensure the product is perfect at launch. This unity tends to fall apart as teams scale up. At 100 people, you sort of care about your team members, but you wouldn’t be too torn up if one of them looked bad in front of the boss or missed a deadline. Their well-being is just not at the front of your mind. More than that, though, as team size rises, unity becomes a daunting challenge. ‘No man left behind’ transforms to ‘every man for himself.’”

Small teams can become more specialized.

In today’s workplace, there’s still value in knowing a little bit about a lot of things, but in many cases, it’s much more important to know a lot about a very particular area.

Small teams can get to this level much faster than large ones.

“It’s frustrating and time consuming to bring a large group of people up to speed on a focused, maybe even technical, subject,” notes Karlgaard. “You can’t move on until everyone understands the task at hand and the challenges you’re facing. The fewer people there are, the more streamlined the process becomes.”

They don’t waste your human resources.

It’s hard to say no when someone wants to join a team, especially when they have a good reason.

“C’mon, I have more institutional memory than Morgan over there.”

“I’ve sold more of this product than 90 percent of the people at that table.”

“This would be a great learning experience for me.”

And so on.

Yet, can your company afford to spread its people so thin?

Often, says Karlgaard, the answer is no.

“When you allow an unlimited number of people to join a team, you may think you’re being transparent, maximizing your brain power and generally creating your best odds for success,” he says. “But chances are, a lot of them are not actively contributing. They’re actually wasting time that could be much better spent on other projects. When you whittle teams down to a small core group, you help ensure that everyone else is using their time and energy more productively.”

Small teams foster mentoring.

Even in smaller teams, it’s likely that members will have different backgrounds, experience levels and areas of expertise.

In fact, says Karlgaard, "two-pizza" groups are a great environment for more experienced people to teach and coach less experienced ones.

“I’m not saying that mentors need to take time away from the project to help develop mentees — though that’s certainly an option you may want to consider,” he comments.

“A lot of the mentoring will happen organically as the team members work together and interact. This is good for the team’s productivity and for your company overall, because you’re developing more junior people without spending any extra resources. Plus, mentoring fosters engagement on both ends: Mentors feel that their skills and knowledge are appreciated and respected; mentees appreciate the personal attention they get as they work with in-house experts.”

Small teams weaken the glass ceiling.

In small teams, everyone has to pull their weight, or else.

There’s no room for favoritism, bureaucracy or old boys’ club politics.

When everyone’s collective neck is on the line, it’s in everyone’s best interests to listen to all opinions and back the best ideas, no matter the gender, race, background, sexual preference, etc., of the originator.

And it’s easy to see how that benefits your organization.

“Of necessity, small teams become meritocracies,” confirms Karlgaard.

“On the other hand, though, we’ve all seen large teams devolve into oligarchies, or even not-so-benevolent dictatorships. Those types of groups not only inhibit progress, they can actively poison your company culture and contribute to the disengagement of valuable employees who, for whatever reason, aren’t part of the ‘in crowd.’”

“Remember, lean and hungry is always better than fat and comfortable,” Karlgaard concludes. “Yes, it may take a lot of work to switch to 'two-pizza' teams if your organization is currently clogged by overcrowded conference tables, and you may run into a lot of resistance. But like SAP and many other companies I’ve encountered, you’ll find that the effort is worth it. Small teams are the high-performance strategy of the 21st century.”
